摘　　要：The selective oxidation of phenylethane with air catalyzed byμ oxo bis manganese porphyrins was studied . It is shown that the main products are hypnone andα phenylethanol . The selectivity of products at alpha position is 100％ . With by extending the reaction, the amount by product increase , the selectivity atα phenylethanol descends and that of hypnone slightly increases, but the total selectivity decrease. With the temperature raising, the yield of hypnone andα phenylethanol relevantly increase, but their selectivity descends. A 3h induction period appeared when the solvent was benzene and chlorobenzol, and they have no influence on the yield of the products;No induction period was obseves when the solvent was butanone and cyclohexanone, and it makes the yield of products increase .The selective oxidation of phenylethane with air catalyzed byμ oxo bis manganese porphyrins was studied .
